Since 1995 we have been successfully producing our aluminium 100/4 cylinder heads.  In 2003 we took the decision to upgrade our product. We went  back to the drawing board and started with completely new CAD drawings to ensure accuracy and perfect detail in our product. We then further enhanced this ‘design to manufacture’ investment philosophy by including state of the art CAM software. When it comes to machining, we have seen a huge upgrade to our capabilities with the acquisition of a brand new 5 axis CNC machining centre in 2010.

For more information on our new cylinder heads and how we can improve your cars performance please see below or contact our Sales personnel.

TYPES OF CYLINDER HEADS

• BARE HEAD
  Fully machined bare head (as cast ports) with valve inserts fitted and semi-formed seats. Ready for you to supply and fit valve guides, cut seats, final skim head gasket face and assemble with your components. (Must use 6 cylinder exhaust valves).

• STANDARD COMPLETE
  Supplied ready assembled by us in our own factory. Bronze valve guides, stainless steel valves, steel valve top caps and heavy duty springs etc. All as listed on page 14. Head gasket face final skimmed giving a combustion chamber of 62cc as original.

• FAST ROAD COMPLETE
  As ‘Standard’ with the addition of gas flowed ports, all symmetrical and matching. Aluminium valve top caps, competition valve springs and top hat stem seals. 62cc chamber volume.

• FULL RACE COMPLETE
  As ‘Fast Road’ with larger ports, for increased flow. The significantly larger exhaust ports are best suited to a large bore manifold gasket and big bore exhaust. They also benefit from dowel holes machined in the manifold face to match the inlet manifolds precisely to the ports. 62cc chamber volume. Both inlet and exhausts ports are hand fettled after CNC machining to achieving the desired surface finish and gas flow characteristics.

PLEASE NOTE: If intending to use any of the above with our roller rockers (CENG502K) please specify with order to have push rod holes machined to suit.
